The short version

  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Google Cloud Platform the $300 Free Trial credit expires 90 days from signup, whichever comes first with spending it
  • They diverge on capability: Cilium covers eBPF datapath, Google Cloud Platform covers Compute Engine.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cilium

  • Requires a recent Linux kernel, which rules out older distributions and some managed environments
  • eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
  • Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

Google Cloud Platform

  • The $300 Free Trial credit expires 90 days from signup, whichever comes first with spending it
  • Free Tier Compute Engine is limited to one non-preemptible e2-micro instance per month and only in the us-west1, us-central1 or us-east1 regions
  • Free Tier Compute Engine includes only 30 GB-months of standard persistent disk and 1 GB of outbound North America data transfer per month
  • Free Tier Cloud Storage covers 5 GB-months of regional storage in US regions only, 5,000 Class A and 50,000 Class B operations per month
  • Free Tier outbound data transfer allowances exclude destinations in China and Australia
  • Compute Engine resources are governed by allocation quotas that require a quota increase request to exceed

Questions people ask

Is Cilium or Google Cloud Platform better?
Neither clearly leads. Cilium starts at Free and Google Cloud Platform at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Cilium or Google Cloud Platform?
Cilium starts at Free and Google Cloud Platform at Free.
Does Cilium or Google Cloud Platform run on more platforms?
Cilium runs on Kubernetes, Linux. Google Cloud Platform runs on Web, Api, Cli.
Can I use Cilium for free?
Both have a free tier, so you can try either at no cost before committing.
What is Cilium best used for?
Cilium is most often used for kubernetes networking at a scale where iptables-based cni performance degrades, network policy expressed on workload identity rather than fragile ip rules, seeing which services actually talk to each other, and what policy is dropping. Of those, kubernetes networking at a scale where iptables-based cni performance degrades and network policy expressed on workload identity rather than fragile ip rules are not what Google Cloud Platform is typically brought in for.
What can Cilium do that Google Cloud Platform cannot?
Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Google Cloud Platform covers Compute Engine, App Engine, Cloud Run, Cloud Storage.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

Yes, open source and CNCF-graduated. Isovalent sells an enterprise distribution and support.

Google Cloud Platform: What is Google Cloud Platform's pricing model?

Google Cloud uses usage-based pay-as-you-go pricing with options for committed use discounts at 1-year or 3-year terms, which can reduce costs by 25-70%. Pricing varies by region, service, and usage volume.

Cilium: What does eBPF change?

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

Google Cloud Platform: Does Google Cloud offer a free tier?

Yes, Google Cloud offers an always-free tier with generous free allowances for development, plus $300 in free credits for new customers during their first 90 days.

Source
Cilium: Does Cilium replace a service mesh?

It can cover much of what a mesh does without sidecars, though full mesh feature sets still favour Istio or Linkerd.

Google Cloud Platform: How do committed use discounts work?

Users can commit to 1-year or 3-year usage of specific services to receive discounts of 25-70% compared to on-demand pricing. These discounts apply to compute, storage, and other services.
